How to make my intercom smart (can unlock by application)

Hello

I wonder if I can make my video intercom smart ?

The screen is wireless.
The outside unit is a doorbell with code and camera connected to the inside screen by 6 wires.
Support mobile phone to unlock by application (I can also connect to the outside unit and watch a live camera).
